Title: You Tube vid quality
Post by: Dillwhacker on July 07, 2016, 12:29:39 AM
Can anyone explain why..
When I upload a decent quality 1080p vid from a Mobius to You Tube, the HD quality seems to be retained (although it takes forever, obviously).
But if I start with a poor quality VGA noisy vid from my goggles, You Tube seems to compress it even more, and make it much worse?
I'd like to be able to see the best I can from the low quality source...is there anything I can do to get You Tube to preserve the (low) resolution?
Cheers !

In the past I've imported my DVR footage into Movie Maker and rendered it at one of the 720p modes that has a higher bitrate than the original file. This itself does not make the image any better, but when I upload to Youtube it seems to be a bit clearer than if I just uploaded the raw file off the DVR.

I would assume your HD footage would have a decent bitrate, whereas your DVR footage would have a much lower bitrate. Youtube's compression might not appear to have much of an effect on a high bitrate video file, but the same amount of compression on a lower bitrate file will be much more noticeable.

Im with BF on this....I noticed the same effect after doing some annotation inside Windows Movie Maker on a raw fpv dvr recording.....In Movie Maker after you get done editing, it gives you the option to save it as a U -Tube friendly file.
  You can see this Bixler 2 clip on my channel....looks as good on the Tube as the original did, if not better.....The key to it all I found is getting your fpv camera setup right with WDR on, and enough brightness set....another is ensuring a good signal from vrx to dvr...
  Some of my earlier recording were utterly crap I should add, but it was cured after experimenting with settings / cables....not " upgrading"

Cheers BF and ET.
I'll look into using a vid editing suite - all new to me - only ever recorded, viewed & uploaded.
The U-tube-friendly file format sounds the ticket.
I think the camera setup is good, WDR on, good brightness & contrast as the pic is great in the goggles and the raw DVR playback is good at home, it just seems to get screwed by Utube.
Cheers guys.
